Photosymbioses: A Coincidence of Evolution?
The new working group "Photosymbiosis" investigates the coexistence of host animals and algae - the European Research Council provides funding of 1,489,000 euros

Government representatives, international organizations, scientists, NGOs and many more are meeting in Cali, Colombia, until 1 November to develop strategies to protect biodiversity and negotiate concrete measures. Dr Ute Jacob from the HIFMB Transfer Office has an official observer status and is on site in Cali.
For many of us, unless it is part of our everyday work, the seabed is probably a space we think little about. But the seabed, as the recent decision by Norway to undertake mining within its national waters revealed, is a space where accessibility and usage rights are contentious and political. This becomes even more profound when we start to ask about the seabed beyond national jurisdiction where there is a lack of clear ‘ownership’. To whom does the seabed belong?
Slowly the impressive lance sinks into the ice. It reminds of a Jules Verne-like scientific instrument in the way its copper plates are bolted so craftfully. It is attached to an enormous installation with howling diesel-powered engines that breathes a slow primitive power. Maybe exactly the type of primitive power and patience that is needed to melt through 100m thick shelf ice. We are in the Antarctic standing on the Eckstroem Iceshelf and we are melting holes to finally revive our passive acoustic observatory after a 2-year data gap due to an ice shelf break off in February 2022.
Do we have sufficient reference data and the appropriate methods and techniques to identify the biodiversity of marine fauna in the dynamic waters of the North Sea using genetic traces from seawater? The aim of a study by the HIFMB Focus Group Marine Molecular Ecology was to evaluate these uncertainties and to bring the method of environmental DNA (eDNA) metabarcoding into application for monitoring and questions on marine conservation in the North Sea.
Two detailed presentations (held in German), developed by two young scientists, enable teachers to find an exciting introduction to the topic of marine biodiversity with their pupils. Specifically, they deal with whale research, the food web in the Antarctic and the special ability of whales to hear and utilise sound waves.
Mirrors is a sound installation that follows the acoustic journey of the Minke Whale as it travels from Antarctica to Namibia. A collaboration between artist-researcher Geraint Rhys and Marine Acoustic scientist Dr Ilse van Opzeeland it charts how the vocalizations of the Minke changes with a change in location as it migrates across the oceans.
Deep-sea mining is a potential new industry in which non-renewable resources could be extracted from the bottom of the deep sea. However, as little is known about the ecosystems of these depths and the impacts of this industry, the prospect of mining these resources poses a great risk.
Every litre of seawater is full of genetic material from all kinds of different organisms. Biologist Silke Laakmann and her team are pioneering techniques that use these DNA traces to determine the biodiversity of marine communities.
My summer spent at the Helmholtz Institute of Functional and Marine Biodiversity (HIFMB) has broadened my horizons and strengthened my research skills. The HIFMB allowed me to explore new areas of research and further develop my interests in advancing how we communicate complex scientific topics to the public.
